The properties stored with hidden points are:
• Class: MEAS
• Sub class: Hidden Point
• Source: Bearing-Distance, Double Bearing, Double Distance, Chainage-Offset or
Backwrd Brg-Dist depending on the hidden point measurement method used
• Instrument source: GPS
An average is calculated for hidden points if a point of class MEAS already exists with the
same point ID.
Refer to "22.7 Hidden Point" for information on how to configure hidden point measurements.
<Azimuth:> is used throughout this chapter. This should always be considered to also mean
<Bearing:>.
Auxiliary points are used to compute azimuths required for the calculation of hidden point
coordinates. Auxiliary points can be points existing in the job or they can be manually occu-
pied. The point ID template configured for <Auxil Pts:> in CONFIGURE ID Templates is
applied. Refer to "19.1 ID Templates" for information on ID templates.
